The Oxylator® functions with two
distinct functional elements (pressure/flow) during a ventilatory
cycle. The first is similar to the inspiratory phase described in
pressure cycled devices described above, with one important and
fundamental difference: the Oxylator® has the capability
to provide adequate ventilatory volumes when a patient has high
airway restriction or poor lung compliance. This is possible due
to the fact that the Oxylator® incorporates a patented
feature which allows the user to increase and optimises the pressure
limit during inspiration prior to switching to the expiratory phase.
This feature is not found on any other resuscitator presently available.
Therefore, the claims made in recommendations as to the inability
of inadequate volume delivery DOES NOT apply to the Oxylator®.
The fact that one particular functional phase is similar to another
device's should not be grounds for evaluation of functional criteria.
In a recent discussion with Dr. A. Sinclair of the Bureau of Medical
Devices (Canada), he confirmed the need to define the Oxylator®
under a new category in order not to misrepresent the Oxylator®'s
capability as done under a "pressure cycled" category.
As mentioned above, the system has two specific
elements which trigger each of the inspiratory/expiratory phases.
The first, is the pressure limiting during the inspiratory cycle,
this initiates the expiratory phase. The second is flow (exhalation),
during the expiratory phase, the Oxylator® will NOT start
a new inspiratory cycle until exhalation phase is complete. This
eliminates the complications which result from "stacked breaths".
The end of the expiratory phase then triggers the next inspiratory
cycle, hence the new INSPIRATORY PHASE IS FLOW TRIGGERED.
